Shintoyotomi Sengoku Kokorozashi 1 (Rekishi Gunzo Shinsho)

[Machine Translation] In October of Tensho 14, Tokugawa Ieyasu finally arrived in Kyoto. The purpose was to make his vassalage to Hideyoshi Toyotomi known to the whole nation. However, on the eve of the audience, Hideyoshi visited Ieyasu's lodgings and was assassinated by secret orders from Tokugawa family vassal Tadatsugu Sakai. Ieyasu, though he did not intend to, had no choice in the matter and immediately returned to Mikawa to prepare for the battle for the country. Meanwhile, Toyotomi Hidekatsu, who was only 19 years old, was nominated as the successor by the Toyotomi faction after the death of their leader. But Hidekatsu was no ordinary young man. He was the son of Oda Nobunaga, the supreme ruler of Japan, and was adopted by Hideyoshi at the age of nine, and had grown up to be an outstanding person befitting the son of two great "fathers. Thus, Hidekatsu was forced to enter into a fierce battle with Tokugawa Ieyasu, the great leader of the Tokugawa shogunate.
